Y., ASSIGNOR TO GROOVE LOCK CO. INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK FASTENING DEVICE Application filed September 24, 1929. Serial No. 394,813.

This invention relates to fastening devices, the invention being more particularly related to fastening devices of the kind suitable for use in connection with ladies? and misses handbags, pocketbooks or other articles requiring simple and efficient means wherebyto secure two parts or sections of the article together or release the same.

An object of the invention is the provision of an improved fastening device of the character described, and one which will have improved and simplified means for securing the, parts of the device together and as well for releasing them.

Another object of the invention is the provision of a fastening device composed of few parts, cheap to manufacture and easy to apply and assemble, and which will, when assembled, possess the characteristics of neatness, strength, durability and symmetry. I

Other objects of .the invention will appear hereinafter. g

The invention consists in the improved fastening device and in the form, construction and arrangement of parts, which will be hereinafter more fully described and subsequently incorporated in the subjoined claims.

For a full understanding of the invention, reference is to be had to the accompanying drawings, which form a material part of this specification, and in which Fig. 1 represents a fragmentary front elevational view'of an article equipped with my improved fastening device;

Fig. 2 represents a section taken on the line 22 of Fig. 1; r s

Fig. 3 represents a cross section taken on line 33 of Fig. 1;

"Fig. i represents a detailed perspective view of one of the parts of the fastening device, the button member being omitted;

Fig. 5 represents a detailed perspective part of the fastening device; and

Fig. 6 represents an elevation of a modified form of construction in which a stop is provided at each end of the rail.

The preferred form of construction, as

illustrated in the accompanying drawings, comprises a plate 10 placeable over a plate 11, the plate 10 constituting an essential part of the fastening device and being secured to the cover or flap 12 of the article, while the plate 11 constitutes another essential part of the device and is secured to the wall or body portion 13 of the article.

In the illustrative embodiment, the plate 10 is represented as being provided with two concavely curved notches 14 and 15 and with a keeper portion or edge 16 separating the two notches. As herein represented, a plate 17, corresponding in shape and size with the plate 10 is united with the latter by means of a transverse connection 18 which joins the corresponding portions 16 and 19 of the two plates. As best illustrated in Fig. 5, the two plates 10 and 17 are connected in spaced apart parallel relation 4 so as to embrace the opposite sides of the flap or cover 12 which in practice is folded over the body portion or wall 13. The two plates 10 and 17 may be secured to the flap or cover 12 by means of rivet devices 20 or any other means suitable for the purpose.

To one face of the plate 11 are soldered or otherwise secured the prong devices 21 which are taken through the wall or body portion 13 and then bent thereupon as shown in Fig. 2, whereby the plate 11 is secured in place fiatwise upon the wall or body portion 13. Said plate 11 is provided lengthwise thereof with a rail 22 of T-shaped form in cross section as will appear from an inspection of Fig. 8. Mounted upon the head of this rail for sliding movement therealong is a button member 23, herein disclosed as including a shell 24 fashioned to produce underneath parts 25 parallel with the face of the plate 11 and flange parts 26 slidably embracing the head of the rail as clearly shown in Fig. 3. Arranged within the shell, as bestshown in Fig. 2, is a spring member 27 having an outwardly bowed portion 28 protruding through an opening 29 in the base of the shell, so as to have frictional engagement with the top of the head of the rail. Said spring permits the button memher to he slid along the rail and at the same onlyfl between the stops, 32- andl33 can be. passed only through the'concave notch 14,

time affords means for. maintaining the buttonrmember in the position to which it is moved. 7 r a The plate 11 is represented as provided with an outwardly projecting pin 30 receivable in .a recess or keyway 31 provided in the plate 17, and these parts are so .posi-fl tioned that when the flap or cover 12 is fo-l,d. ed o ver the wallor body portion 13 with the pin 30 enteredin the recess 31, the keeper edge 16 will be parallel with but spaced from the head of the rail, and in thisvrelationship the concave notches 14 and 15 constitute escape openings adjacent the rail.

Said concave notches 14 and 15 are of a size to permit the button member to pass therethrough. .The rail; 22isfprovided at onejend thereof with a stop 32for the but-,

tonv member; and when the buttonmeinber is moved into position to abutthel stop 32, itcan be passed throughthe concave notch 14 to, permit the. application orremoval of the plate 10. 'When .the plate has been placed overtheplate. 11- with the recess 31 receiving the pin .30, the, button member may be slid along the railand over the keeper edgel6 whereby to secure the parts together-against lateral separationone out wardly from the other.

2 In theembodiment of the invention, illustratedin, Fig. 4, the rail is provided, with a stop 33 to limit the movement of the but-. ton. to that position where it .will be in proper engagement over the keeper edge 16.

i In this form of construction, it-Will be manifest that the button, member, being slidable the gother concave'notch being-provided in this instance only for 11164111113988 of in-.

suringa well-balanced andsymrnetrical device. [If r desired, I however, other concave notch 15niay beomitted V In the modified form of construction a shownin' Fig. 6 the stop 33' has beenelimi nated, while the mills provided with an.

end stop 34 againstwhich the button member .may, be moved when it isto be passed throughthe concave notch 15, In this form of v constructiomthe button member may be moved from the keeper edge against the stop 82 V for. escape through the concave notch 14,01 it may be moved into the oppoe I site direction against the stop 341for escape through the concave notch 15. From the foregoing descriptlon, taken in connection with the accompanying drawing, 7 it w llbe seen that l have provlded a very simple, practical and efiicient. fastening device, andjonegwhich is composedof few parts, cheap to manufacture, apply and assemble. Y

It will be manifest that I have disclosed a thoroughly satisfactory, form of fastening devicewhich embodies the features of ad vantage enumerated in the statement of invention, and while I have, in the present instance, shown and described certain preferred embodiments of the invention as reduced to practice, it is to be understood that the constructions are susceptible of modification in various particulars without departing from the spiritor scope of my invention or sacrificing any of its advantages,
